 MacRumors Forums How to solve a math problem

For example: Code: `1: 0 2: 1 3: 2 4: 0 5: 0 6: -2 7: -1` This arrangement satisfies all the conditions (x in this case happens to be 5). What I want to know is how many unique orderings are possible, given the value of x and the conditions above. __________________ iMac Intel (Rev H, 27"), 1TB HDD, 16GB RAM, 10.8.4 0
